cassandra cluster loadbalancing
hello there,
Can you tell me please how can I loadbalance my canssandra cluster. When I
do nodetool status I can see that the load is not loadbalanced among my
cassandra nodes
Datacenter: datacenter1

Hi Sara,
I am not sure why you say that this is unbalanced, such small amounts of
data are not relevant. It depends of too much factors (keys inserted,
compaction that ran or are to run...)
You should use "nodetool status *myks*" to see if your tokens are well
distributed - column "Owns (effective)" - and review your model to see if
your data is going to be evenly spread between the nodes.
C*heers,
Alain
